Insulating oil, also known as transformer oil, is an oil with superior electrical insulation qualities that is stable at high temperatures. Oil in a transformer is primarily used to create electrical insulation between the various live parts. Transformer oils provide enhanced electrical insulation and high-temperature stability and also prevent oxidation. Insulating and cooling a transformer are the main purposes of transformer oil. It must, therefore, possess high thermal conductivity, chemical stability, and dielectric strength, and it must maintain these qualities even when exposed to high temperatures for an extended period of time. They typically have a pour point below 40 °C (40 °F), a flash point above 140 °C (284 °F), and a dielectric breakdown at more than 28 kV RMS. The oil-filled tank may have external radiators through which the oil circulates by natural convection in order to improve the cooling of large power transformers. Transformer oils also expand at high temperatures and contract at low temperatures. For 1,000 liters of oil and a temperature difference of 50°C, this amounts to 35 liters. Transformers thus have an expansion reservoir. Depending on the type of construction, this is provided with dry cartouches, which extract humidity from the air.
